Adjusting the LNB Skew Angle
(Linear Polarization Only)
LNB Skew Angle
The LNB skew angle only needs to be adjusted when the target satellite
is linear polarized. In order to receive the maximum satellite signal level,
the LNB skew angle must be adjusted according to the calculation of
current GPS location and target satellite.
It only needs to be adjusted when changing from one satellite to
another, or when the vessel has traveled a signicant geographic
distance. It should NOT need to be readjusted if the vessel stays in the
same location and is operating on the same satellite.
Skew Angle Adjustment of i3/i3L/i4
Polarization of your Intellian i3/i3L/i4 antenna must be accomplished
manually by the following steps.
1. Open the radome after switching power OFF.
2. Loosen 4 bolts of the connection of LNB and feed horn.
3. Turn LNB to place it to the angle indication of the back of the feed horn.
4. Tighten the 4 bolts.
5. Re-install the radome .
